Peter Jackson is shooting "The Hobbit" in New Zealand right now, so perhaps he's too busy to catch wind of the serious fighting words that were thrown down at the Cannes Film Festival last week.

They came from Lynne Ramsay, the film director behind the feature film "We Need To Talk About Kevin," which created some of the hottest buzz at the fest. But she also spent a lot of time talking about one of her former almost-movies, "The Lovely Bones," which she has a bit of a history with.

Ramsay was originally attached to adapt the novel as early as 2001, sticking with the project until, in her words, Steven Spielberg started poking around, and then she left and Jackson inevitably ended up taking over in 2004.

And let's just say she wasn't too big of a fan of Jackson's take on Alice Sebold's story: "I thought it looked like 'My Little Pony,'" she said.

Turns out Ramsay hasn't seen the entire film (which scored 32 percent rotten on Rotten Tomatoes), but she didn't like what little she has seen.

"I saw the trailer and I thought it looked like... terrible," she told MTV News at Cannes. "I thought it was completely trite and not what I was doing [in my adaptation] in any way. I was going for something a lot more psychological."
